Neutrinoless double beta decay, the inverted hierarchy, and precision determination ofθ12

2011

Ruling out the inverted neutrino hierarchy with neutrinoless double beta decay experiments is possible if a limit on the effective mass below the minimal theoretically possible value is reached. We stress that this lower limit depends strongly on the value of the solar neutrino mixing angle: it introduces an uncertainty of a factor of 2 within its current 3σ range. If an experiment is not background-free, a factor of two in effective mass corresponds to a combined factor of 16 improvement for the experimental parameters running time, detector mass, background level and energy resolution. Therefore, a more precise determination of θ 12 is crucial for the interpretation of experimental results and the evaluation of the potential and requirements for future experiments. We give the required half-lifes to exclude (and touch) the inverted hierarchy regime for all double beta decay isotopes with a Q-value above 2 MeV. The nuclear matrix elements from 6 different groups and, if available, their errors are used and compared. We carefully put the calculations on equal footing in what regards various convention issues. We also use our compilation of matrix elements to give the reachable values of the effective mass for a given half-life value. *

We present accurate predictions of the effective Majorana mass |m ββ | in neutrinoless double-β decay in the standard case of 3ν mixing and in the case of 3+1 neutrino mixing indicated by the reactor, Gallium and LSND anomalies. We have taken into account the uncertainties of the neutrino mixing parameters determined by oscillation experiments. It is shown that the predictions for |m ββ | in the cases of 3ν and 3+1 mixing are quite different, in agreement with previous discussions in the literature, and that future measurements of neutrinoless double-β decay and of the effective light neutrino mass in β decay or the total mass of the three lightest neutrinos in cosmological experiments may distinguish the 3ν and 3+1 cases if the mass ordering is determined by oscillation experiments. We also present a relatively simple method to determine the minimum value of |m ββ | in the general case of N -neutrino mixing.

“…As already emphasized, our approach describes axially symmetric deformed nuclei. As an example for a deformed nucleus, we consider 76 Ge, a nucleus of particular interest in the neutrinoless double β-decay experiments in the past [41,42], present [43], and future [44].…”

Gamow-Teller strength in deformed nuclei within the self-consistent charge-exchange quasiparticle random-phase approximation with the Gogny force

2014

The charge-exchange excitations in nuclei are studied within the fully self-consistent proton-neutron quasiparticle random-phase approximation using the finite-range Gogny interaction. No additional parameters beyond those included in the effective nuclear force are included. Axially symmetric deformations are consistently taken into account, both in the description of the ground-states and spin-isospin excitations. We focus on the isobaric analog and Gamow-Teller resonances. A comparison of the predicted strength distributions to the existing experimental data is presented and the role of nuclear deformation analyzed. The Gamow-Teller strength is used to estimate the β − -decay half-life of nuclei for which experimental data exist. A satisfactory agreement with experimental half-lives is found and justifies the additional study of the exotic neutron-rich N = 82, 126, and 184 isotonic chains of relevance for the r-process nucleosynthesis.

IGEX76Geneutrinoless double-beta decay experiment: Prospects for next generation experiments

Abstract: The International Germanium Experiment (IGEX) has analyzed 117 mole yr of 76 Ge data from its isotopically enriched (86% 76 Ge) germanium detectors. Applying pulse-shape discrimination (PSD) to the more recent data, the lower bound on the half-life for neutrinoless double-beta
